Where are all the PS3s?

So this is odd. In reading up on Final Fantasy XIII, I decided to see how much it would cost to buy a PS3 and the game. The system is all but sold out all over the Internet! It’s backordered on Newegg, GameStop, and Best Buy (partially), and can be found on Amazon for quite the mark-up—there’s no way I’m paying $370 for the 120GB SKU. Did the Sony factory lose power or something, or is Final Fantasy XIII that big of a system-seller?
